Putting a backer plate in an inaccessible area
Here is how I fixed an unwanted hole in the transom of a foam-filled boat.
- I drilled a ½” diameter hole on each side of the unwanted hole,then used a saber saw to connect the holes to form a slot.
- Next, I cut 4mm thick plywood into a football-shaped backer plat that would fit through the slot the narrow way. I attached strings to the plate, coated it with epoxy then slipped it through the slot.
- Using the strings, I turned the plate so that it covered the three holes and the slot. Reference marks on the plate helped me get it in the right position.
